Electrical engineering is the study of the laws of electrical energy and the principles of engineering in order to apply them to the generation, transmission, and use of electricity. With knowledge of electrical phenomena and technology, those trained in electrical engineering can design everything from power generating systems in dams to tiny electronic circuits for spacecraft, as well as electronic components that run computers, televisions, stereo systems, and automated factories. Four well-recognized branches of electrical engineering in which individuals may concentrate include power, communications, electronics, and control systems. Other areas recognized by the Institute of Electronics and Electrical Engineers for career possibilities include circuits and devices, industrial applications, electromagnetics and radiation, computers, engineering and the human environment, and signals and applications.

Electrical and electronics engineers design, develop, test, and supervise the manufacture of electrical and electronic equipment. Some of this equipment includes power-generating, controlling, and transmission devices used by electrical utilities, as well as lighting and wiring in buildings, automobiles, aircraft, radar and navigation systems, computer and office equipment, and broadcast and communications systems.
